Hi, Omar. We do not know which shaft seal used with that Intex Pump. You will need to contact Intex 1(800)234-6839.

What is the correct shaft seal replacement part for a Hayward Super pump II with a salt system. The service technician will replace all the required O-rings. If I purchase a replacement motor and a new shaft seal, is there anything else that I need to purchase for the tech. (besides O-rings)

A  Answered on 5/31/2019 by InyoPools Product Specialist Hector F.

It sounds like you have all of the commonly needed items. The saltwater shaft seal for the Super II is 5250-235.

Just want to confirm that this is the same as SPX2700SA, but for saltwater pools.

A  Answered on 2/12/2019 by InyoPools Product Specialist Lennox H.

Hi, Michael. This PS-3867 is NOT the same as the SPX2700SA. The Shaft Seal, Viton 5/8" - PS-3890 is the generic heavy duty option.

What is the difference between a chlorine pool and a soft water with regard to the seal?

A  Answered on 7/4/2018 by InyoPools Product Specialist Alex V.

Dan, Salt-water is more corrosive to equipment so it is recommended to use a heavy duty shaft seal. Other wise, the seal will fail prematurely and cause damage to the motor.

will this fit ao smith 1 hp square flag 56y motor

A  Answered on 9/8/2016 by InyoPools Product Specialist Scott W.

It will depend on the model of your pump, not your motor. The motor can go to several different model pumps, so would need to know the model of your pump to determine the correct shaft seal.

?     Asked on 6/11/2016 by Joe

should I replace the seal every time I replace the motor?

A  Answered on 6/11/2016 by InyoPools Product Specialist Patrick P.

Yes we suggest replacing the shaft seal whenever you replace your motor as the old seal sometimes does not mate up properly with the new motor. Also the warranty on the motor is voided is there is leaking to due the seal.

Why should I purchase the heavy duty seal?

A  Answered on 1/17/2012 by InyoPools Product Specialist Patrick P.

The heavy duty shaft seal features carbon graphite, stainless steel, and Viton rubber. The properties of this seal contribute to the resistance of chemical corrosion. This is the best choice for salt chlorine generators or ozonators.

Leaking shaft seal

Written on 8/1/2018 by Guest

Existing shaft seal was leaking (salt water pool) and found out my previous repair guy did not put in a heavy duty seal for salt water. Ordered the replacement from INYO and had it here in a couple of days. Disconnected the power from the motor, removed the pump faceplate and housing from the motor. Easily removed the diffuser and impeller following the instructional INYO video and replaced the seal shaft. Put everything back together in reverse order and fixed the leak.
